Zotac GTX590 SLI 5760×1080 Nvidia Surround Review

Dirt 2

A very strange set of results greets us in Dirt 2. The single screen GTX590 doubles the frame rate of the HD6990. Doubles it. Yet when we plug in the other two screens the HD6990 takes a mind-blowing 20 FPS lead.

Even odder the SLI setup has over 100% extra performance when compared to the single card. All very weird.
